HAMILTON.

HAMILTON, Ala. -- Prosecutors are in contact with a former classmate of John Mark Karr because she has a yearbook signed at him more than 20 years ago that may reveal the answer to individual of the mysteries of the JonBenet Ramsey ransom note -- what does "SBTC" stand for?

In the yearbook, Karr signed the classmate's page and finised his missive with the line, "Though difficult in the future, maybe I shall be the conqueror and live in multiple peace."

The words "shall be the conqueror" do not appear anywhere as an acronym, unless they are written in upper-case characters.

The 2oe-page ransom note was left with the Ramseys the day JonBenet was killed. The note [i]finale[/i]ed "Victory! S.B.T.C."

from one side an e-mail and phone conversations, Boulder Colo district attorney's investigators have been in touch with the classmate for the last married pair of days on the matter.
